When it comes to the Grammys, we tune in for the performances. Aside from the night's top categories — Album of the Year, Best New Artist, Song of the Year, and Record of the Year — the Grammys are all about the show-stopping performances, from the unexpected collaborations, to the emotional ballads, and breakthrough live sets, and the 2014 Grammy Awards will be no exception. 

The First Couple of hip-hop — Jay Z and Beyonce — will take the stage together at the 56th Grammy Awards, along with Grammy newbies Macklemore & Ryan Lewis (who will be performing with Madonna), alternative teen phenom Lorde, hitmaker Pharrell Williams (who will be performing with Daft Punk and Stevie Wonder), pop stars Katy Perry and Taylor Swift, and legends Paul McCartney and Ringo Starr. You can also expect performances from Bruno Mars, Sara Bareilles and Carole King, Hunter Hayes, Keith Urban, Kacey Musgraves, John Legend, Robin Thicke and Chicago, a surprising collaboration between rapper Kendrick Lamar and alt-rockers Imagine Dragons, and Pink and Nate Ruess. Foo Fighters frontman Dave Grohl will be closing out the night with a rock supergroup, featuring Nine Inch Nails, Queens of the Stone Age, and Lindsey Buckingham of Fleetwood Mac.

Check out the full list of performances below! Who are you most excited to see? Sound off in the comments!
